Abstract This paper describes measurements of concentrations of cosmogenic 26 Al, 10 Be and 21 Ne in quartz from bedrock surfaces in the Transantarctic Mountains where stratigraphic and geomorphic evidence shows that the surfaces were covered by ice in the past, but were not glacially eroded during...
